The shape of the lip suggests that this entity is probably a semipeloric form. Seidenfaden (Nordic J. Bot. 14: 293-301. 1994) provides commentary that suggests that its closest relative is Chamaegastrodia asraoa (J. Joseph & Abbareddy) Seidenfaden & A. N. Rao, an Indian species now regarded as a member of Odontochilus; if so, the validity of Chamaegastrodia as an independent genus is questionable.
